Can I bolt up a Transfer Case to a 2wd transmission no problems? If not why?

2 ways to do it.................

1-Tear apart transmission and change the rear output shaft with the shorter 4wd output shaft and replace the longer 2wd rear cone with the t-case adapter.

2-Buy a 4wd transmission.

Any idea which option would be the most cost effective?

You could also try option 3, trade your's in on a 4X4.

I was originally going to do that but I decided I just want to do a solid axle swap and then all I really get from buying a 4x4 is the trans and tcase (which would be nice) but I think keeping what i have is the best route for my project.

Not sure what your mechanical skills are, but you'll have to tear the transmission apart all the way beginnning at the bell housing right down to the output shaft, which is the last part on the other end, i.e. pull all the guts out. The good thing is, is you don't need anything except for a couple gaskets and tranny fluid, and a free day to do it.

It would have to be easier to buy a tranny/t-case combo than to mix & match. I assume you have the 42-series tranny. That has to be the most numerous combo available which should keep price down a bit and availability up a bit.

Yes I do have the 42series. I believe I am just going to hunt for a good deal for the next couple months and see what I come up with.

So, if I happened to find a rolled 02-07-ish 4x4 KJ that I could pick up for $500... What all would I need to steal from the rolled KJ to convert my 07 2WD to 4WD?

To make it easier, lets assume the rolled one has a 42RLE like mine.

Swap Tranny plus transfer case, CVs, 2WD/4WD gear shifter,

What else? Electronics?? Can the wiring harness for the electronics be removed as a single harness, or is it part of a much larger wiring harness?

The rolled KJ is only $500? Let me know the details if you don't end up purchasing it.

You would need a '07 KJ,any other will not work since they changed almost everything in '07.Granted the trans and t-case is the same but the wiring and communication is vastly different.

Yeah. I was afraid of that. It would probably be easier to adapt an 08-09 KK to mine than the 02-06 KJs.

I guess I will just keep my eyes open.

But... If I were to find an a totaled 07, what would I need to swap?

A KK won't work. First it uses a new t-case and then somewhere between 08 to 09, the ignition system changed on the KK. I also believe that the wiring in the KK is different since the TCM is part if the ECM and since the t-case is controlled by the BCM

Have a 2WD tranny but need a Tcase on it.
